Does removing a file extension corrupt a file (in Windows)?

I am trying to send an executable file to a friend, but her ISP is rejecting it due to fear of it being a virus (which it is not). If I remove the .exe extension from the file name and have the recipient add it to the file name on her end, will there be any corruption in the file? I am just trying to bypass her ISP's security measures.

i have had this problem in the past and zipped the offending .exe file with winzip and it got through the other end successfully.

i think your idea of appending the suffix may work, give it a try by sending yourself a test ??

It doesn't "corrupt" the file, but Window's won't know what program to use to open the file. The person who gets the file will need to put the .exe back on the end to run it.

I usually change the .exe to a .txt when sending stuff via e-mail.
No. A corrupted file is one where part or all of the data in the file has been scrambled. In reality changing the file extension is only changing the name of the file. It is still there, the data is still intact, but the programme that uses it may not be able to find it.

It can be changed back just as quickly with the "rename" command in Windows.
